The TPS65123RGTRG4 from Texas Instruments is a DC-DC converter specifically designed to supply the voltages required by amorphous-silicon (a-Si) and low-temperature poly-silicon (LTPS) TFT-LCD displays. This device utilizes a compact design with a single inductor to generate independently regulated positive and negative outputs.
A free-running variable peak current PWM control scheme time-multiplexes the inductor between outputs. This control architecture operates at a pseudo-fixed frequency, providing fast response to line and load transients while maintaining a relatively constant switching frequency and high efficiency across a wide range of input and output voltages. The high switching frequency capability allows for the use of inexpensive and ultra-thin 8.2 or 10 µH inductors.
Key electrical specifications include an input voltage range of 2.5V to 5.5V, an adjustable output voltage up to 5.6V with a minimum of 3V, and an output current of 25 mA. The quiescent current is 181 µA, and it features 4 regulated outputs. The device operates within a temperature range of -40°C to 85°C.
The TPS65123RGTRG4 is housed in a 16-pin VQFN package and is suitable for surface mounting. It is supplied on tape and reel. Environmental compliance includes RoHS3 compliance and Lead-Free status.
